CompTIA A+ Core 2 (220-1202) — Question 140

A technician completes the installation of an OS that appears to be successful. However, when the technician removes the USB drive that was used for the installation and restarts the system, the following error appears:

No OS found.

Which of the following should the technician do next to resolve the issue?

Answer options

• A. Reinstall the OS from a new ISO image.
• B. Enable UEFI devices in the BIOS.
• C. Restart in recovery mode and troubleshoot.
• D. Install the storage drivers for the motherboard.
• E. Reseat the SATA cable.

Correct answer: B

Explanation

The correct action is to enable UEFI devices in the BIOS, as the system may not be set to boot from the correct device after installation. The other options, such as reinstalling the OS or troubleshooting in recovery mode, do not address the likely misconfiguration in the BIOS settings that is preventing the OS from being detected.
